Thank you for clicking on my post. I do not have a good level of English, so I hope I did not make too many mistakes. All feedback welcome !

So, here is my idea of SCP: a human (perhaps female, I do not know yet) who would go into a trance at the sight of an act of violence (from a simple friendly shot to a shootout). He (she) will then seek by all means to return the device to the aggressor and will not calm down once its task accomplished. I suppose he (she) should be classed Keter.

I was thinking of adding to the SCP a healing power for the victims.

Despite the capabilities of the entity, it would be able to learn to control its powers. A protocol could be put in place to help and prevent incidents.

What if said act of violence was done in self-defense? Or towards an inanimate object? I've seen people kick cars and trash cans when upset.

I suppose he (she) should be classed Keter.

This admittedly seems kind of like a reverse 096, since instead of following people down to kill them, this thing follows people around to help them?

I'm personally not sure about this. Why does this entity have these healing powers? Why do they go around helping people who are only involved in violence, as opposed to illnesses or natural disasters?

It feels like right now, the idea isn't very strong. I want to know more about why and how this thing became the way it is, not just what it is. People will be able to relate more to human characteristics, not just the powers. No one reading this site actually has powers.

Well, first, dissociation triggered by an act of violence isn't even really anomalous. That seems like something that could happen to real people. The 'healing factor' and 'she gets control over it' lead it into X-men territory, which isn't really the focus for the Foundation. I also don't really see the point of the cross-testing at the moment.

He (she) will then seek by all means to return the device to the aggressor and will not calm down once its task accomplished.

I'm sorry, but I have no idea what this even means. I don't know what device you're talking about, and it seems like you're saying it'll keep freaking out after it's done.
